JAMES WATSON, or MARINETTE, wisconsin.v

isrnIm-srovnl Be it known that I, JAMES WATSON, a citizen of the United States, residing at Marinette, in the county of Marinette and State of Wisconsin, have inventedy a new and use-v ful F ield-Stove, of which the following is a specication. v Y y The device forming the subjectmatter of this application 'is a stove, adapted to be used by troops in the field, by campers and others, under conditions which call for a stove capable of being collapsed readily and stored in small compass, so asto occupy but little space when theoccasion for its luse has passed.

The invention aims tol provide -novel means for connecting lthe central andv y side sections of the stove, to provide novel means for directing the productsof combustion through the stove, to provide novel means whereby the re may be held in proper relation to the stove, and to improve generally, and to enhance the utility of devices of. that type to which the invention appertains.

l/Vith the above and other-.objects inview, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it beingunderstood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention. i

ofthe doors; Fig; 12 is a fragmental sectional detail showing the mounting of'one of the keepers and Fig. 13 is a sectional `detailA illustrating 'a modified means for holding they fuel in place.

Referring to the drawings, wherein a preferred 'but' not mandatory form of the invention is shown,the numeral 1 has been used to designate a central section including a top 2 which is suitable f trussed as shown :at 3.

4The numeral 4 marks a"foldable stack attached to 'the top 2 of the central section 1 .by any suitable means as shownat 5. The ,foldablestack 4 and the securing means 5 has not been shown indetail, norwill they bey discussed at length, because they are not new to thisapplication. 4The top 2 is supplied at its extremities withA depending flanges? The numeral 8 denotes a rear wall, and the numeral 9 marks a front end wall, these walls being hingedas shown at 10 to the flanges 7 ofthe top 2 ofthe central section v1. d The top 2, the anges 7, and the walls 8 and' 9 areprovided with projecting lips"11. Arod12 is -pivoted at 14 to the frontend wall 9 and carries a rectangular prong. 15. `The rod 12 maybe used as a .prop to hold 4the front end wall9in an openzposition when the same is swunglupward and outwardly'on the corresponding hinges 10.` If. the prong 15 on the rod 12 is embedded in the earth, then the front end wall 9 will be held in a closed position. The .front end wall 9 may be supplied witha downwardly openingv door 16, connected with the front wall by means of hinges 17. `The upperedge'of the door 16 is adapted to coact with a keeper 18 carried by the end ,wall 9. A latch-19 is mounted to .swing on the endwa'll 9 and -ris'adapted to overhang the door 16 to hold the latter firmly closed during transportation, and under other conditions which will suggest themselvesto fthe user.- The'door 16y is supplied with a seat 20, wherein the free end of the latch 19 Ais Y The fiue 106 comprises a bottom 107 and sides 108 hinged to vthe bottom as shown at 109, the sides 108 having reinforcing flanges 110, and there being notches 111 in the sides 108 at' the ends of the flanges 110. The flue 106 in the condition shown in Fig. 10 is inserted at its ends into the spaces 60a of the two side sections 22, as will be understood readily when Fig.'4 is compared with Fig-1, the channel members'28 being re'- ceived in the notches l111. A depending bafe 6 is assembled with the top 2 ofthe central section 1 and extends downwardly into the flue 106, to the bottom 107 thereof between the sides 8, the flanges 110v bearing against the under surface of the top 2 of the 'central section 1. It will now be understood that the products of combustion, rising within the central section 1, pass laterally, in opposite directions, through the spaces 60 and longitudinally of the sections 22, between the tops'rof the ovens and the tops 23 of the sections, the products of coinbustion ultimately flowing toward each other, into the flue 106, until the baille or separator 6 is encountered, whereupon the products of combustion will find an exit through the stack 4. Since the casings 54 are spaced as shown at 57 from the tops 23 of the parts 22, the heat will pass, to some extent, above the casings 54. The general construction is such that the ovens 44 will be heated evenly, and this result is produced, in no small degree, owing to the presence of the flue 106 and the separator or baffle 6.

An angular plate 61 extends around the lower inner edge of the oven 44, and is secured thereto, an asbestos strip 62 being interposed between the plate 61 and `the oven. The numeral 63 marks an angular plate provided along its longitudinal edges with hook-shaped flanges 64 engaging the longitudinal edges of the plate 61, these edges of the plate 61 being oflset slightly from the oven, as shown-in Fig. 2, so as to coperate with lthe hook-shaped flanges 64 of the plate 63. At this point it may be stated that thev plates 61 and 63, together with the protector comprising the parts 48 and 50, serve to shield the contents of the oven from being burned, it being obvious, when the description progresses, that ythe heat isgreatest at the lower inner edge of the oven. .A keeper 71, the functions of which will be mentioned hereinafter, is journaled for rotation in the plate 63, and may bear against the-plate 61, as shown in' Fig. 12, there being nuts 115` on they keeper 71, On opposite sides` of the plate 63. The vinner nut 115 may be heldv with a pair of pliers whereupon the keeper 61 maybe removed from the plate 63, the keeper no longer bearing on the plate 61. rlhen, the plate may be struck upwardly and outwardly at its angle, so as to free the flanges 64 of the plate 63 from` the longitudinal edgesof the plate 61. 'In thisway., the platev 63 may be renewed at any time, should it become damaged, pitted, or burned away. During the operation which consists in renewing the plate 63, the side section preferably is Vdetached'v'fromthe central section Y1, and is turned upside down, so that the Workmen may operate advantageously. v v

A fxeddeflector 65 is attached to the end walls 25 and 24 and slants downwardly from the'outer side wall 26v as clearly shown in Fig. 2. Aniovable orfadjustabledeector 66 is hinged at 67 to .the inner edge of each fixed deflector 65. The movable defiector 66 is supplied at its ends with upright wings 68 hinged to the' movable deflector at 69. In t-he edges of the wings 68, notches 70 are formed, .the notchesbeing adapted to -engage theflanges 43 on the lower edges of the uprights k42. The keeper 71:, hereinbefore mentioned, .coperates with the inner edge of the deflector 66,]under conditions,

and for arpurpose, which willbe set forth hereinafter.

In practicalA operation, the side sections are; supportedl onrthe surface v77 of ythe ground, the centralsection 1 beingl carried by the side sections, in the way hereinbefore described. The movable deflector 66 lis disposed inalinement with the fixed deflector 65, and. the surface of the groundmay Abe inclined, as indicated at 78,` to `receive the movable deflector. The wings 68 upstand, and the; notches 70 are engaged with the parts 43 on the lower ends of thel uprights 42, lthe-wings 42 thus being held in upright positions to prevent the earth from sliding inwardly and interfering with the fire or with the products of combustion as they pass upwardly along the, deflectors y66 and 65.

inclined or dugaway as indicated at 79, to

receive the sides 73 of the grate, a platform 80, cutinto the soil, serving to support the legs 74, the grate, in this way, being held in the-position shown in Fig. 13.` In the platform 80, an opening is dug,` and Yin this opening-81 is disposed a tubular ash p it 82, the outline of which has been indicated in Fig. 3. The ash 'pit 82 preferably is made ofsheet metal and includes any desired num; loerofl g sections detachably connected as shown at 83. `When the ash pit 82 is in the l fixed leflectors 65 and ground, the pit is of tubular construction, but itis possible to collapse the pit and pack it away,

A water tank 84 is disposed against the end wall 8 of the central section 1, the water tank. including a lid 85. Y

VAlthough vthe grate may be omitted as shown in Fig. 2, it maybe used when desired, as shown in Fig. 13, andwhen the grate is employed, the ashes falling-through the grate, will-,be received in the pit 82. The fuel, preferably is stoked through the door 16, or into' the end of the central section 1 if the wall'9 is raised and propped up by the rod` 112.9 VAccess is had to the ovensA 44 by way ofthe doors 29. l

The structure shown set up in Fig. 1 of the drawings maybe collapsed and packed away 'sor as tooccupy but` little space. Thus, the v vaterV tank 84 may be slid into one of the ovens 44. The central section 1 may be detached from the side sections22, and the ends 8 and 9 of the central section may be folded with respect to the top 2 of the cen.- tral section. Similarly, the stack 4"may be detached from the top 2. of the central section, and be folded. When the stack is folded, it Vmay be placed'between one 4of the the bottom of the corresponding oven 44. The flue 106Lmay be folded and stored away in a similar way'. The movable deflector 66 may be: swung upwardly andl be engaged by the keeper 71 when the latter is rotated, and', thus, the stack 44 the lue`106 or any other desired articles may be held in place against the bottoms of the' ovens 44 by the deflectors 65 and 66. The ash pit'82 may be collapsed and be stored away in any convenient or accessible place. The particular way in which the parts are housed when thestructure is knocked down willbe understood readily by thosel skilled inthe art,.and will be dictated to some extent, b the operation which the user wishes to fol ow. When the stove is in a collapsed form, it consists, essentially, of but three parts, to'lwit, the folded side sections 22 andy the folded central section 1. j
